Be it known that I RLCHARD Woonccclpf the town ot' Joliet, 'n'Will county, 'and State of Illinois, have invented a new and useful improvement on a Tile and Pipe Machine; and I do hereby declare that the followinibr is a full andfexact description of the construction and operation of thesame, reference being had to the annexed drawings, making a part of this specification, in Which- Figure 1 is a perspective View. i

Figure 2, a longitudinal elevation; and

Figures 3 and 4, diilercnt views of the part called the receiver.

I co1 struct the png-mill a i a cylindrical form, placing the sainevin` a horizontal position, furnished with n main shaft,b, with the-ordinary blades and screws for working' the cla-y and pressing it toward the aperture atoneend; from whence issues the tile.' 'The particular part of themill that I call new, as `distinguished from that which is old, is the sclf-revolvingvcore shaft c, with the core e permanently attached thereto, and forming a part thereof, running through the entire length of the lrolloiv inain shaft I), as show n in tig. 2, by means of which thc core e is held in its proper position without any possibility of' its getting,` out of the centre of thc aperture in thc die plate f. The core shaft is held in its place in the main shaft by a nut, g, at the outer end, and, being loose in said shaft,` revolves by the pressure of' the clay as it passes from the mill around the core e, through the aperture in the centre of the die plate fwith a spiral motion imparted by the screws of' the main shaft, in. consequence of which the core is less liable to tear the tile or pipe as it emerges from 'the machine than Vwhen itis made to revolve by other means. The core being attached to so long a shaft is eiectnally prevented from wabbling, and preserves' a uniform thicknessof the walls otlvthe tile. For the purpose of' receiving the tile or pipe from the mill I use the -receiver z', 3 and 4, and Iig. 1,-) which consists of a concave or half cylinder, of' a diameter and length to correspond with the required size ofthc tile or pipe. The concave is set in a bed or frame, as is shown in figs. 3 and 4, with guides at each corner for the purpose of' guiding a Wire to cnt the tile or pipe oifat the ends. In gll the receiver is shown as receiving a tile from' the machine. The receiver rests when receiving the tile or pipe inthe fralnc m, (fig. 1,) on the ron` ot' rollers n, so that after lit has received the tile or pipe it mayy slide away from the mill lto give pla'cc to another receiver for the next-tile or pipe. The receiver is also used to carry Vthe `tile or pipe from the mill, and for turning them on end, ivhile in the green state, to dry, as shown in fig. 4. I Claim.

What I ola'im as my invention, and desire tov secure by Letters Patent,

1. The self-revolving core shaft c in the hollow main shaft Z7. v

2. The receiver z', answering the double purpose of receiving the tilepfrom the mill and handling the saine While in a vgreen state.

3. A combination of the' self-revolving core shaft c, thc main shaft and the receiver wh en used and operating substantially as described. l
